The age of the moon rock can be calculated by calculating the half-life. The moon rock is 3.75 billion years old. The correct option is B.
What are meteorites?
A meteorite is a solid that is made up of dust or rock. The meteorite is falling from the galaxy. On falling they catch light and heat, so they seem to burn when falling from the sky.
The number of half-life would be:
parent molecule/child molecule
(1/2)^(half-live)
5/40= (1/2)^(half-live)
1/8= (1/2)^(half-live)
(1/2)^3=(1/2)^(half-live)
half live= 3
age= half-life count x half-life duration
age= 3 x 1.25 billion years = 3.75
Thus, the correct option is B, 3.75 billion years old.
